Somebody help. 2003 F-250 Powerstroke 7.3 6 speed
Have an irritating buzzing sound and feel in the relay for the blinkers/brake when the ignition is turned on. I replaced the relay and still getting the buzz. Blinkers still work and the buzz stops when I turn the blinker on or when I hit the brakes. Anybody please.

 

Its the turn signal arm, or the harness connecting the arm to the relays. ive heard sometimes its too short from the factory and partially unpluggs (tilt steering), take the colum covers off and see if its plugged in all the way at the arm and follow the wires down the colum and make sure its all plugged in tight, if its not then you probably have to buy a new arm, i think it comes with new harness? Mine did it too but i was able to wiggle the wiring around after taking it apart and made it stop,

 

I had this same issue with a low battery charge just today. I cleaned and charged the batts and the buzzing went away.

 

Thanks Gentlemen. Late tonight so will look into it tomorrow. Will keep you informed. Thought it was possible low voltage coming in but never thought about too short of wiring. Thanks again
